Multi channel H.264 HD to RF ATSC DVBT DVBC ISDBT digital cable tv encoder modulator

Product Description

Q3 This platform, with H.264 video encoding mode by default, supports MPTS/SPTS/ASI independent multiplexing output and IP out channel switch.

With PSI/SI technology to modify the audio and video PID information of the output program, Q3 also supports to insert a NIT information table into the WEB to achieve better compatibility with the backend device.

Q3 encoder modulators with OSD/Logo/QR code Insertion function, which perfectly suit any professional SD/HD Video company, including TV Channels, Live broadcasters, Government applications, Hotel, Campus, Entertainment facilities, education broadcasting systems at schools and government buildings and many others.

Highlights

• Works both Coax Cable & IPTV networks: Distribute MPEG-4 AVC encoding to all kinds of Modulation and All SPTS/ MPTS Over UDP IP out.

• Operation via LCD Screen and Web Management : easy to read LCD color front panel that makes it easy to setup and monitor your channels, check firmware, and identify IP addresses without a computer.

• Multi-Modulation: Optional DVB-C (QAM), DVB-T (COFDM), ATSC-T, ISDB-T, DTMB Modulation (can selectable in one device).

• Flexible selection of different input modules: four tuner, four HD- MI encoding in one device.
